Description

  The present invention relates to a machine tool adjustment system, an adjustment method, a program, and an adjustment value for specifying an adjustment value for adjusting a plurality of supports that support the machine tool so that the inclination of a predetermined surface of the machine tool is equal to or less than a predetermined inclination. It relates to machine tools.

  Machine tools such as a portal type five-sided machine are installed on the upper surface of a table provided above the table, a bed supported on the ground by multiple supports, a table movable in a predetermined direction on the bed And a head for processing the workpiece. Since the machining position of the workpiece is determined by moving the table, in order to improve the machining accuracy of the workpiece, the inclination of the upper surface of the table is within a predetermined range over the entire stroke of the table (for example, several tens of micrometers per meter). It must be less than the slope of the meter). The adjustment (leveling) of the inclination of the upper surface of the table is performed by adjusting the height of the support that supports the bed.

  However, when the height of the support is adjusted, not only the inclination of the point supported by the support but also the inclination of the surrounding points change. Further, the relationship between the change in the height of the support and the change in the inclination of the upper surface of the table differs depending on the difference in the cross-sectional shape of the bed with respect to the moving direction of the table, the type of the machine tool, and the like. Therefore, the leveling of machine tools requires knowledge and technology based on the experience of workers, and the number of workers that can be appropriately leveled has been limited.

  In Patent Document 1, the static accuracy of a machine tool is calculated, an adjustment value of a stroke indicating the length of the support with the floor is calculated based on the calculated static accuracy, and the support is performed based on the adjustment value. Techniques for adjusting the body are disclosed.

As a result, the data recording device 133 records the displacement in the X-axis direction and the roll angle and pitch angle of the upper surface of the table 13 for each predetermined displacement in the X-axis direction (step S1). The adjustment value display device 126 displays the roll angle and pitch angle for each displacement of the table 13 recorded by the data recording device 133.

  The operator visually determines whether the inclination of the upper surface of the table 13 displayed on the adjustment value display device 126 is within an allowable range (step S2). That is, the operator determines whether or not all the roll angles and pitch angles for each displacement of the table 13 displayed on the adjustment value display device 126 are values within a predetermined allowable range. Note that this determination may be displayed not to the worker but to the worker by, for example, automatically determining with the processing device 24 and displaying the result on the adjustment target value display device 125. When it is determined that the inclination of the upper surface of the table 13 displayed on the adjustment value display device 126 is within the allowable range (step S2: YES), the adjustment process of the leveling jack 11, that is, the leveling process of the portal machine tool 1 Exit.

  On the other hand, when it is determined that the inclination of at least one portion of the upper surface of the table 13 displayed on the adjustment value display device 126 is not within the allowable range (step S2: NO), the operator presses a predetermined button, etc. Thus, an instruction to start adjustment is input to the portal machine tool 1. The adjustment target value specifying unit 1135 of the portal machine tool 1 that has received the adjustment start instruction generates an inclination matrix P indicating the inclination of the upper surface of the table 13 based on the information recorded by the data recording device 133 (step S3). ). For example, the first row element of the inclination matrix indicates the roll angle at the first displacement of the table 13, the second row element indicates the pitch angle at the first displacement of the table 13, and the third row element Indicates the roll angle at the second displacement of the table 13. Similarly, each element of the inclination matrix P indicates a pitch angle and a roll angle for each displacement in the X-axis direction.

Next, the adjustment target value specifying unit 1135 reads the transfer function T from the transfer function storage unit 111, and calculates its pseudo inverse matrix (step S4). Note that the pseudo inverse matrix T ⁺ may be stored in the transfer function storage unit 111 in advance. In this case, the calculation in step S4 is unnecessary, and the time required for the calculation, that is, the waiting time of the worker is eliminated, so that the workability can be improved.
Next, the adjustment target value specifying unit 1135 calculates the adjustment value matrix X by multiplying the gradient matrix P generated in step S3 by the pseudo inverse matrix T ⁺ calculated in step S4 (step S5). Each element of the adjustment value matrix X indicates an adjustment value of each leveling jack 11. For example, the element on the first line indicates the adjustment value of the first leveling jack 11, and the element on the second line indicates the adjustment value of the second leveling jack 11.

  The adjustment target value specifying unit 1135 specifies the value of each element of the adjustment value matrix X as the adjustment target value of each leveling jack 11. Next, the adjustment target value display device 125 displays the adjustment target value of each leveling jack 11 specified by the adjustment target value specifying unit 1135 (step S6).

  Next, the operator attaches the stroke sensor 123 to the leveling jack 11 to be adjusted from now on. When the operator adjusts the stroke of the leveling jack 11, the stroke sensor 123 detects the adjustment value and outputs it to the adjustment value display device 126. Thereby, the adjustment value display device 126 displays the actual adjustment value of the leveling jack 11. Then, the operator adjusts the stroke of the leveling jack 11 so that the stroke value displayed on the adjustment target value display device 125 matches the adjustment target value of each leveling jack 11 displayed on the adjustment target value display device 125. (Step S7). This operation is repeated for all leveling jacks 11 to be adjusted.

  After the operator finishes adjusting the strokes of all the leveling jacks 11, the operator moves the table 13 of the portal machine tool 1 in the X-axis direction again. Thereby, the data recording device 133 records the roll angle and pitch angle of the upper surface of the table 13 for each displacement in the X-axis direction after adjusting the stroke (step S8). The adjustment value display device 126 displays the inclination of the upper surface of the table 13 recorded by the data recording device 133.

  The operator determines whether or not the inclination of the upper surface for each displacement in the X-axis direction of the table 13 displayed on the adjustment value display device 126 is within an allowable range (step S9). Note that this determination may be automatically displayed by the processing device 24 instead of the worker, and the result may be displayed on the adjustment target value display device 125 to be displayed to the worker. When it is determined that the inclination of the upper surface for each displacement in the X-axis direction of the table 13 displayed on the adjustment value display device 126 is within the allowable range (step S9: YES), the leveling process of the portal machine tool 1 Exit.

On the other hand, when it is determined that the inclination of the upper surface of the table 13 displayed on the adjustment value display device 126 is not within the allowable range in a certain displacement in the X-axis direction (step S9: NO), the operator uses the portal machine tool 1. Is instructed to start readjustment. For example, the instruction may be given by pressing a button provided on the adjustment value display device 126. As a result, the transfer function updating unit 1134 to which the readjustment start instruction signal is input, the inclination of the upper surface of the table 13 recorded by the data recording device 133 in step S1, and the table recorded by the data recording device 133 in step S8. A difference with the inclination of the upper surface at each of the 13 corresponding displacements is taken (step S10).
Thereby, the transfer function updating unit 1134 specifies how much the inclination of the upper surface of the table 13 has actually changed due to the adjustment by the operator.

Next, the transfer function updating unit 1134 changes the actual inclination specified in step S10 and the inclination change obtained from the transfer function T (the value obtained by multiplying the adjustment value of the leveling jack 11 by the transfer function T). ), The transfer function T stored in the transfer function storage unit 111 is updated to a relational expression closer to the actual condition (step S11). The transfer function updating unit 1134 can calculate the change in the actual inclination obtained by actually adjusting the leveling jack 11 from the transfer function T by inputting the adjustment value of the corresponding leveling jack 11. Update.
When the transfer function T stored in the transfer function storage unit 111 is updated by the transfer function update unit 1134, the process returns to step S3, and the portal machine tool 1 recalculates the adjustment target value.

Here, an example of a transfer function update method will be described.
A tilt angle change that actually occurs on the upper surface of the table 13 when a stroke change as displayed on the adjustment target value display device 125 is applied to all leveling jacks 11 is detected by the inclinometer 121. The change in the tilt angle can be expressed by a tilt angle vector _Preal on the upper surface of the table 13. Stroke vector _{X real} inclination angle vector _{P real} Each stroke sensor 123 indicating the stroke change of the leveling jack 11, is a known value by inclinometer 121. Here, the following equation (1) is established between the stroke vector _Xreal and the inclination angle vector _Preal . The tilt angle vector _Preal is an (m × 2n) × 1 column vector indicating the pitch angle and roll angle of the inclinometer 121 for each displacement in the X-axis direction of the table 13 (where m is the size of the table 13). M = 1, 2, 3 .. That is, if the combination of two inclinometers 121 for measuring the tilt angles corresponding to the roll angle and the pitch angle is one on the table, m = 1. If there are two, m = 2, if three, m = 3, etc. Further, n indicates each displacement of the table from 1 to n in the X-axis direction). The stroke vector _Xreal is a 2N × 1 vector indicating the stroke (length) displacement of the jacks arranged at equal intervals in the X-axis direction (N is the leveling jack 11 of 1 to N in the X-axis direction). Position).

The element in the i-th row of the inclination vector P _real is P _real (i), and the element in the j-th row of the stroke vector X _real is X _real (j). When the length of the jack stroke corresponding to the value indicated by _Xreal (j) is adjusted for only the jth jack corresponding to the jth row of the stroke vector _Xreal , the bevel vector of the inclinometer 121 When the variation of the inclination angle at the position of the i-th row of P _real (i denotes any of 1 to m × 2n) is to be represented by _{P real} (i),
P _real (i) = T _real (ij) × X _real (j) (1)
It can be expressed as. T _real (ij) represents an element in the i-th row and j-th column of the transfer function T _real . The transfer function _Treal is a vector of 2 nm rows and 2N columns.

Accordingly, the element T _real (ij) in the i-th row and j-th column of the updated transfer function T _real can be obtained by Expression (2).

T _real (ij) = P _real (i) / X _real (j) (2)

As an example of another transfer function updating method, even if the transfer function is updated by using the transfer function T _cal stored in the transfer function storage unit 111 (that is, the transfer function obtained by analysis such as the finite element method). good.

Here, the relationship among the adjustment value matrix X _cal obtained in step S5, the transfer function T _cal, and the target value P _cal of the tilt angle of the table is expressed by the following equation (3).

P _cal = T _cal × X _cal (3)

Here, the worker performs the adjustment work so that X _real matches X _cal while referring to the display of the adjustment target value display device 125. That is, the following formula (4) is established.

X _real = X _cal (4)

  From these, the following formula (5) is derived.

P _cal = T _cal × X _real (5)

Then, the transfer function updating unit 1134 can calculate the updated transfer function T _real based on the equation (6) derived from the equations (1) and (5) described above.
T _cal (ij) −T _real (ij)
= {(P _cal (i) −P _real (i)) / X _real (j)} (6)

In the same way as described in the equation (1), in the equation (6), the element in the i-th row of the inclination vector P _real is P _real (i), and the element in the j-th row of the stroke vector X _real is Let _Xreal (j). When the length of the jack stroke corresponding to the value indicated by _Xreal (j) is adjusted for only the jth jack corresponding to the jth row of the stroke vector _Xreal , the bevel vector of the inclinometer 121 the i-th row of P _real (i is one showing the 1 to m × 2n) is the variation of the inclination angle shown by _{P real} (i) at the position of.

  Thus, according to the present embodiment, the transfer function update unit 1134 predicts the actual change in inclination due to the adjustment according to the adjustment target value specified from the transfer function and the change in inclination obtained from the transfer function. The transfer function is updated by comparison with. As a result, the transfer function is corrected as compared with the case where the transfer function is corrected by changing the adjustment value of each support point one by one and performing the operation of discriminating the difference between the measured value and the model. Man-hours for work can be greatly reduced.

The server device 110 includes a transfer function storage unit 111, a transfer function transmission unit 112, a data reception unit 113, and a transfer function update unit 114.
The transfer function storage unit 111 uses the transfer function indicating the roll angle displacement and pitch angle displacement of the upper surface of the table 13 when the stroke of the leveling jack 11 is changed by the unit adjustment amount as the model and installation conditions of the portal machine tool 1. Store it in association.
The transfer function transmitting unit 112 receives a transfer function transmission request associated with the type and installation conditions of the portal machine tool 1 to be adjusted from the portal machine tool 1.

The adjustment value of each leveling jack 11 is specified based on the function.

Next, a displacement adjustment method using the machine tool adjustment system 100 according to the second embodiment will be described.
In 1st Embodiment, the portal machine tool 1 demonstrated the case where the adjustment target value was specified and the said transfer function was updated using the transfer function recorded on the transfer function memory | storage part 111 with which an own apparatus is provided. In the second embodiment, the portal machine tool 1 has a transfer function that matches the type and installation conditions of the portal machine tool 1 to be actually adjusted among a plurality of transfer functions stored in the server device 110. Is used to specify the adjustment target value and update the transfer function.

  First, before adjusting the portal machine tool 1, the operator inputs the type and installation conditions of the portal machine tool 1 into the condition input unit 1131 using an input device such as a keyboard. Next, the transfer function acquisition unit 1132 requests the server apparatus 110 for a transfer function associated with the input model and installation conditions. The transfer function transmission unit 112 of the server device 110 reads a transfer function that matches the type and installation conditions included in the request from the transfer function storage unit 111 and transmits the transfer function to the portal machine tool 1. Then, the adjustment target value specifying unit 1135 calculates a pseudo inverse matrix in step S4 of the flowchart shown in FIG. 3 based on the received transfer function.

  After that, when it is determined in step S9 of FIG. 3 that the inclination of the upper surface of the table 13 is not within the allowable range, the data transmission device 136 stores the stroke change amount stored in the storage medium 134, the roll angle of the upper surface of the table 13, and The change amount of the pitch angle is transmitted to the server device 110. Then, the data receiving unit of the server device 110 receives the information, and the transfer function updating unit 114 corrects the transfer functions in steps S10 and S11 in FIG.

  As described above, according to the second embodiment, since the server device 110 updates the transfer function, the accuracy of the transfer function for each type and installation condition is increased. Can be shortened.

<< Third Embodiment >>
Next, a machine tool adjustment system 200 according to the third embodiment will be described.
FIG. 6 is a schematic block diagram illustrating a configuration of a machine tool adjustment system 200 according to the third embodiment.
The machine tool adjustment system 200 according to the third embodiment is different from the second embodiment in the parameter of the adjustment value of the leveling jack 11. In the second embodiment, the stroke of the leveling jack 11 is used as a parameter of the adjustment value of the leveling jack 11, but in the third embodiment, the compression load of the leveling jack 11 is used.

Therefore, the transfer function of the third embodiment is a matrix whose elements are the roll angle displacement and the pitch angle displacement of the upper surface of the table 13 when the compressive load of the leveling jack 11 is changed by the unit adjustment amount. Further, the adjustment value matrix of the third embodiment is a matrix having the compression loads of the leveling jacks 11 as elements.
Further, the portal machine tool 1 of the third embodiment includes a load sensor 127 that measures a compressive load acting on the leveling jack 11 instead of the stroke sensor 123.

  According to the third embodiment, the operator adjusts the leveling jack 11 so that the compression load adjustment target value displayed on the adjustment target value display device 125 is equal to the compression load measured by the load sensor 127. By doing so, the machine tool can be leveled.

<< Fourth Embodiment >>
Next, a machine tool adjustment system 300 according to the fourth embodiment will be described.
FIG. 7 is a schematic block diagram illustrating a configuration of a machine tool adjustment system 300 according to the fourth embodiment.
The machine tool adjustment system 300 according to the fourth embodiment specifies an adjustment target value for adjusting the inclination of the bed 12 of the portal machine tool 1. In the second embodiment, the roll angle and the pitch angle are measured for each displacement of the X axis by moving the table 13 in the X axis direction. However, in the fourth embodiment, the displacement sensor 122 and the inclinometer 121 are mounted. By moving the stretcher 128 on the bed 12 in the X-axis direction, the roll angle and the pitch angle are measured for each displacement of the X-axis. The stretcher 128 provided in the portal machine tool 1 is a plate-like jig that is placed on a bed, and the flatness and parallelism of the upper surface and the lower surface are confirmed in advance.

  Thus, according to the fourth embodiment, an operator can level the bed 12 prior to leveling the table 13. In this embodiment, the case where the stretcher 128 includes the displacement sensor 122 has been described. However, the present invention is not limited to this, and the displacement of the stretcher 128 may be specified manually by the operator.

<< Fifth Embodiment >>
Next, a machine tool adjustment system 400 according to a fifth embodiment will be described.
When the sampling number n of the inclination of the table 13 is smaller than the number m of the leveling jacks 11, since the transfer function has redundancy, a combination of adjustment values that can make the inclination angle of the table 13 a desired inclination is a plurality of patterns. Can be identified.

Specifically, when a vector indicating the inclination of the table 13 is set as Θ and a transfer function is set as K, x is calculated as a vector indicating an adjustment target value of the leveling jack 11 by the following equation (7). be able to.
x = K ⁺ Θ + (I−K ⁺ K) ω (7)
Here, I is a unit matrix, and ω is a redundant variable that is an arbitrary vector.

  Based on this, the machine tool adjustment system 400 according to the fifth embodiment is an adjustment target value that can keep the inclination of the table 13 within a predetermined range while suppressing the number of adjustment operations of the leveling jack 11 by the operator. Is identified.

FIG. 8 is a schematic block diagram illustrating a configuration of a machine tool adjustment system 400 according to the fifth embodiment.
A machine tool adjustment system 400 according to the fifth embodiment is different from the second embodiment in the configuration of a processing device 424.
The processing device 424 further includes a redundant variable specifying unit 1133 in addition to the configuration of the second embodiment. Further, the operation of the adjustment target value specifying unit 1435 of the processing device 424 is different from that of the second embodiment.

The redundant variable specifying unit 1133 specifies the redundant variable ω in Expression (7) so that the number of leveling jacks 11 to be adjusted is minimized. For example, the redundant variable specifying unit 1133 specifies the adjustment value matrix x having the highest evaluation value based on an evaluation function that calculates a higher evaluation value as the matrix is sparse. Accordingly, the redundant variable specifying unit 1133 can specify the redundant variable ω that makes the adjustment value matrix x the sparsest, that is, the redundant variable ω that minimizes the number of leveling jacks 11 to be adjusted.
The adjustment target value specifying unit 1435 uses the redundant variable ω specified by the redundant variable specifying unit 1133 to calculate the adjustment value matrix x based on Expression (7). Thereby, the minimum target leveling jack 11 to be adjusted and its adjustment target value are displayed on the adjustment target value display device 125.

  As described above, according to the fifth embodiment, by reducing the number of leveling jacks 11 to be adjusted by the operator, the operator can set the inclination of the upper surface of the table 13 to a predetermined inclination in a short time. it can.

In the present embodiment, the evaluation function of the redundant variable ω is such that a higher evaluation value is calculated as the number of leveling jacks 11 to be adjusted is smaller. However, the present invention is not limited to this.
For example, in another embodiment, the redundant variable ω may be determined using an evaluation function that calculates a higher evaluation value as the total sum of walking distances from when the worker starts adjustment work to when it finishes.
In this case, the work start position of the worker and the walking route and distance from the position to all the leveling jacks 11 are recorded in the storage device in advance, and the redundant variable specifying unit 1133 determines the evaluation value based on the information. calculate. Then, the redundant variable specifying unit 1133 specifies the redundant variable ω having the highest evaluation value. Thereby, the adjustment target value specific | specification part can specify the leveling jack 11 which should be adjusted so that a worker's walk distance may become the minimum.
In another embodiment, an evaluation function that calculates a higher evaluation value as the magnitude of the inclination change of the table 13 with respect to the stroke change of the leveling jack 11 may be used. In this case, for example, the redundant variable specifying unit 1133 specifies the redundant variable having the lowest evaluation value, so that the adjustment target value specifying unit 1435 has the leveling jack 11 that minimizes the sensitivity of the inclination change of the table 13 with respect to the operation amount. It can be an operation target. As a result, it is possible to improve the work efficiency of an operator who is unfamiliar with the work.
Conversely, for example, the redundant variable specifying unit 1133 specifies the redundant variable having the highest evaluation value, so that the adjustment target value specifying unit 1435 causes the leveling jack 11 that maximizes the sensitivity of the inclination change of the table 13 to the operation amount. Can be the operation target. Thereby, it is possible to improve the work efficiency of workers who are used to work.

  As mentioned above, although several embodiment was described using drawing, embodiment is not restricted to this.

  For example, in the second to fifth embodiments described above, the server device 110 includes the transfer function update unit 114 and updates the transfer function. However, the present invention is not limited to this. For example, in other embodiments, the processing devices 124 and 424 may include the transfer function update unit 114 as in the first embodiment. In this case, the server device 110 receives the transfer function updated by the processing devices 124 and 424 from the data transmitting device 136 and overwrites the transfer function storage unit 111 with the transfer function.

  Further, in the second to fifth embodiments described above, the server device 110 receives the amount of change in the actual tilt of the table 13 and the adjustment value of each leveling jack 11 from the data transmission device 136 to transmit the change. Although the case where the function is updated has been described, the present invention is not limited to this. For example, the portal machine tool 1 directly connects the storage medium 134 that records the amount of change in the inclination of the table 13 and the actual adjustment value of each leveling jack 11 to the server device 110, and The transfer function may be updated by reading the information.

  Moreover, although embodiment mentioned above demonstrated the case where an operator adjusted the leveling jack 11 based on the adjustment target value displayed on the adjustment target value display apparatus 125, it is not restricted to this. When the portal machine tool 1 includes an actuator such as a hydraulic jack instead of the leveling jack 11, the actuator is operated with the adjustment target value specified by the adjustment target value specifying unit 1435, so that the upper surface of the table 13 can be operated without human intervention. You may adjust the inclination of.

  Moreover, although embodiment mentioned above demonstrated the case where the condition input part 1131 receives the input of a model and installation conditions from an operator, it is not restricted to this. For example, the relationship between the adjustment value of the stroke of the leveling jack 11 stored in the storage medium 134 and the inclination of the upper surface of the table 13 may be used as information relating to the type or the installation conditions of the machine tool. In this case, the transfer function transmission unit 112 transmits, to the processing devices 24, 124, and 424, a transfer function that indicates the relationship closest to the relationship among the transfer functions stored in the transfer function storage unit 111.

<< Sixth Embodiment >>
Next, a machine tool adjustment system 500 according to a sixth embodiment and a displacement adjustment method using the machine tool adjustment system will be described.
FIG. 9 is a schematic block diagram showing the configuration of a machine tool adjustment system 500 according to the sixth embodiment.
As shown in this figure, in this embodiment, the portal machine tool 1 includes, as an example, four inclinometers 121-11, 121-12, 121- in addition to the components including the table 13 described with reference to FIG. 21, 121-22 and a displacement sensor 122. The four inclinometers 121-11, 121-12, 121-21, and 121-22 are collectively referred to as inclinometers 121. The four inclinometers 121 are installed on the upper surface of the table 13, two at the front and the rear in the moving direction of the table 13 relative to the bed 12. In the present embodiment, two inclinometers 121-11 and 121-12 are arranged in front of the table 13 in the moving direction of the table 13 with respect to the bed 12, and two inclinometers 121-21 and 121-22 are provided. It is assumed that the table 13 is installed behind the bed 12 in the moving direction. For example, in this case, an inclinometer 121-11 installed in front of the moving direction has a pitch angle, an inclinometer 121-12 installed in the front of the moving direction has a roll angle, and an inclinometer 121-21 installed in the rear of the moving direction. An inclinometer 121-22 installed behind the pitch angle and the moving direction measures the roll angle. The number of inclinometers 121 may be increased or decreased as appropriate according to the length of the table 13. For example, when the length of the table 13 is long, a combination of inclinometers 121 for measuring the roll angle and the pitch angle is further set in the center of the table 13 or between the inclinometers 121 installed at the front and rear. One or more sets may be installed. In this case, there are six inclinometers. A larger number of inclinometers 121 may be provided.

The data recording device 133 has the same function as the data recording device 133 described in the other embodiments.
In the present embodiment, the server device 110 includes a transfer function storage unit 111, a processing device 124, and a display device 1251.
The transfer function storage unit 111 stores a transfer function (sensitivity matrix) as described in other embodiments.

In addition to the transfer function updating unit 1134 and the adjustment target value specifying unit 1135 described in the other embodiments, the processing device 124 includes a tilt change target amount calculation unit 1136 and an adjustment tilt amount output unit 1137.
An inclination change target amount calculation unit 1136 uses the adjustment target value specified by the adjustment target value specification unit 1135 to adjust the inclination change target amount of the inclinometer 121 when the length of the leveling jack 11 is adjusted. This is a processing unit that calculates based on the identified adjustment target value 1135 and the transfer function. The inclination change target amount calculation unit 1136 calculates the inclination change target amounts of the four inclinometers 121 for each displacement from the reference position of the table 13 detected by the displacement sensor 122.
The adjustment inclination amount output unit 1137 is an adjustment inclination amount of a predetermined displacement in a given direction of the table 13 when the length of the leveling jack 11 is adjusted after the inclination change target amount is output to the display unit. Is obtained from the inclinometer 121, and the obtained adjustment inclination amount is associated with the inclination change target amount of the predetermined displacement and output.

  The display device 1251 has a function of displaying the tilt change target amount in the above-described embodiment. Further, the display device 1251 has a function of displaying the adjustment inclination amount output from the adjustment inclination amount output unit 1137. For each displacement of the table 13, the display device 1251 indicates that the inclinometer 121 is set when the operator adjusts the leveling jack 11 based on the inclination change target amounts for the four inclinometers 121 and the inclination change target amount. The measured adjustment tilt amount is displayed in association with each other.

  This embodiment is an example in which the stroke sensor 123 is not attached to the leveling jack 11 of the portal machine tool 1. And it differs from other embodiment by the point which makes the operator confirm the inclination change target amount of the inclinometer 121 instead of displaying the target adjustment amount of the leveling jack 11 and making it confirm with an operator.

FIG. 10 is a diagram illustrating a processing flow of the machine tool adjustment system 500 according to the sixth embodiment.
Similar to the above-described embodiment, first, the worker attaches four inclinometers 121 and a displacement sensor 122 to the table 13 of the portal machine tool 1 to be adjusted as an example. However, when the displacement sensor 122 is provided in the portal machine tool 1 from the beginning for detecting the X-axis displacement of the table 13, the attachment work is not necessary. Hereinafter, for convenience of explanation, a case where there are four inclinometers 121 will be described. The four inclinometers 121 may be sensors provided on the table 13 of the portal machine tool 1 from the beginning. The worker inputs an inclination measurement start instruction to the server device 110. For example, the display device 1251 has a touch panel function, and an input button for a tilt measurement start instruction is displayed on the display device 1251, and the operator presses this button. Then, the display device 1251 detects an operation to the tilt measurement start instruction and outputs a signal corresponding to the processing device 124. Then, the processing device 124 detects an inclination measurement start instruction and transmits an inclination measurement start instruction signal to the portal machine tool 1 via the data recording device 133. Note that when the tilt measurement start instruction signal is transmitted to the portal machine tool 1, the portal machine tool 1 controls the movement of the table 13 in the moving direction, but automatically based on the tilt measurement start instruction signal. Instead of the gate-type machine tool 1 controlling the movement of the table 13, the operator may make a judgment by himself and move the table 13 by a predetermined amount manually.

  Upon receiving the tilt measurement start instruction signal, the portal machine tool 1 controls the movement of the table 13 to the reference position (for example, the movement limit position at the end of the movement direction of the table 13) upon reception of the signal (step S100). . Next, the portal machine tool 1 controls the movement of the table 13 in the movement direction of the table 13 from the reference position. The displacement sensor 122 detects the displacement in the X-axis direction from the reference position of the table 13 and outputs it to the data recording device 133. When the operator manually moves the table 13 instead of the process of step S100, the operator displays the display of the displacement value from the reference position of the table 13 acquired by the displacement sensor, such as the display device 1251. And may be input to the data recording device 133 after visual confirmation. At this time, the amount of movement and the number of movement operations per movement operation are determined in advance, and the worker inputs information indicating the completion of one movement operation to the data recording device 133 according to a predetermined procedure. It may be. In this case, the data recording device 133 may automatically recognize the current displacement position of the table 13 by calculation based on the number of times of input of the completion information of the moving operation based on the completion of one moving operation. By doing so, the operator does not need to visually confirm the displacement of the table 13. On the other hand, the data recording device 133 continuously acquires the roll angle or pitch angle measured by each inclinometer 121 from each of the four inclinometers 121 (step S101). The roll angle and pitch angle may be measured by the user visually displaying the output based on the output of the inclinometer 121, and the values may be manually input to the data recording device 133. Further, the data recording device 133 compares the displacement in the X-axis direction from the reference position of the table 13 with each position at a predetermined interval from the reference position stored in advance. When the data recording device 133 determines that the table 13 has reached each position at a predetermined interval from the reference position, the data recording device 133 receives the information on the position and the measurement results of the four inclinometers 121 when the position is reached. 110. When the portal machine tool 1 moves and controls the table 13 to the end opposite to the reference position, the movement control of the table 13 is stopped. Thereby, the measurement result of the inclinometer 121 when the table 13 reaches each position at a predetermined interval provided between the reference position and the end in the moving direction is transmitted to the server device 110. When the portal machine tool 1 stops the movement control of the table 13, it transmits an inclination measurement end signal to the server device 110. Instead of the portal machine tool 1 transmitting a tilt measurement end signal to the server apparatus 110, the operator himself may press the tilt measurement end button to input information indicating the end of the tilt measurement to the server apparatus 110. Good.

  When the server device 110 receives the tilt measurement end signal, the processing device 124 outputs the roll angle and pitch angle for each displacement of the table 13 recorded by the data recording device 133 to the display device 1251. Then, the display device 1251 displays an inclination measurement screen including information received from the processing device 124. The tilt measurement screen displays a table position display field 11-1 for displaying the displacement of the table 13 in the X-axis direction, and a measurement result display for displaying the roll angle and pitch angle for each displacement of the table 13 recorded by the data recording device 133. Column 11-2 exists. At this time, the information received from the data recording device 133 is displayed in the table position display column 11-1 and the measurement result display column 11-2.

  Next, the processing device 124 determines whether or not the inclination of the upper surface of the table 13 displayed on the display device 1251 is within an allowable range (step S102). That is, the processing device 124 determines whether each roll angle or pitch angle measured by each inclinometer 121 for each displacement of the table 13 displayed on the display device 1251 is a value within a predetermined allowable range. It is determined by comparing with a value indicating. When the processing device 124 determines that the inclination of the upper surface of the table 13 displayed on the adjustment value display device 126 is within the allowable range (step S102: YES), the processing device 124 performs the adjustment processing of the leveling jack 11, that is, The end of the leveling process of the portal machine tool 1 is determined, and information indicating the end is displayed on the display device 1251. The determination in step S102 is performed by the operator looking at a roll angle or pitch angle graph (tilt state graph) for each displacement in the X-axis direction displayed on the tilt measurement screen, and as a result, input from the touch panel of the display device 1251. You may make it perform based on the information.

  On the other hand, when the processing device 124 determines that the inclination of at least a part of the upper surface of the table 13 displayed on the adjustment value display device 126 is not within the allowable range (step S102: NO), the adjustment target value specification of the processing device 124 is specified. The unit 1135 generates an inclination matrix indicating the inclination of the upper surface of the table 13 based on the information recorded by the data recording device 133 (step S103). For example, the element in the first row of the inclination matrix indicates the roll angle measured by the inclinometer 121-12 installed in the moving direction when the table 13 is positioned at the first displacement, and the element in the second row is The pitch angle measured by the inclinometer 121-11 installed forward in the movement direction when the table 13 is located at the first displacement is shown, and the elements in the third row indicate that the table 13 is located at the first displacement. Sometimes indicates the roll angle measured by the inclinometer 121-12 installed at the rear in the moving direction, and the element in the fourth row is an inclinometer installed at the rear of the moving direction when the table 13 is located at the first displacement. 121-22 shows the pitch angle measured. Similarly, each element of the inclination matrix indicates the pitch angle and roll angle of the inclinometer 121 for each displacement in the X-axis direction.

Next, the adjustment target value specifying unit 1135 reads the transfer function from the transfer function storage unit 111 and calculates its pseudo inverse matrix (step S104). The pseudo inverse matrix may be stored in advance in the transfer function storage unit 111. In this case, the calculation in step S104 is unnecessary, and the time required for the calculation, that is, the waiting time of the worker is eliminated, so that the workability can be improved.
Next, the adjustment target value specifying unit 1135 calculates an adjustment value matrix by multiplying the inclination matrix generated in Step S103 by the pseudo inverse matrix calculated in Step S104 (Step S105). Each element of the adjustment value matrix indicates an adjustment value of each leveling jack 11. For example, the element in the first row indicates the adjustment value of the first leveling jack 11, and the element in the second row indicates the adjustment value of the second leveling jack 11. Then, the adjustment target value specifying unit 1135 outputs a tilt change target amount calculation instruction including the adjustment matrix calculated in step S105 to the tilt change target amount calculation unit 1136.

  The inclination change target amount calculation unit 1136 multiplies a transfer function and an adjustment value matrix (corresponding to a stroke vector) based on the relationship of the above formulas (1) and (3), and calculates four values for each displacement on the table upper surface. A tilt change target amount vector (corresponding to a tilt angle vector) including an element of the tilt change target amount of the inclinometer 121 is calculated (step S106). Each element indicated by this inclination change target amount vector indicates the pitch angle or roll angle of each inclinometer 121 for each displacement of the table 13 in the X-axis direction. The operator may adjust the leveling jack 11 so that the measurement result indicated by the inclinometer 121 becomes the pitch angle or the roll angle. The tilt change target amount calculation unit 1136 outputs information about the pitch angle or roll angle of each inclinometer 121 for each displacement in the X-axis direction of the table 13 to the display device 1251 based on the calculated tilt change target vector (step 125). S107). Then, the display device 1251 displays a tilt adjustment screen including information received from the tilt change target amount calculation unit 1136. The tilt adjustment screen includes a table position display column 12-1 for displaying the displacement of the table 13 in the X-axis direction, a column 12-2 for displaying a tilt change target amount (described as a target value in the drawing), a tilt There is a column 12-3 for displaying the adjustment amount (described as an actual measurement value in the figure). Before the operator operates the leveling jack 11, a numerical value based on the inclination change target vector calculated by the inclination change target amount calculator 1136 is displayed only in the column 12-2 for displaying the inclination change target amount.

  When the tilt adjustment screen is displayed, the operator presses the tilt measurement button displayed on the tilt adjustment screen. Then, based on the depression of the tilt measurement button in the display device 1251 having a touch panel function, the processing device 124 outputs a signal indicating the start of tilt measurement to the portal machine tool 1 via the data recording device 133. Then, the portal machine tool 1 moves and controls the table 13 to the first first displacement based on the reference position in the X-axis direction. The movement control of the table 13 may be performed manually after the operator presses the tilt measurement button, instead of being automatically performed by the portal machine tool 1 as described above. In this state, the operator operates the leveling jack 11 to adjust the length (the height of the floor and the bed; the stroke). The data recording device 133 outputs the measurement values of the four inclinometers 121 at the first displacement to the server device 110. The processing device 124 displays the measured value of the inclinometer 121 acquired from the data recording device 133 in the column for displaying the tilt adjustment amount on the tilt adjustment screen. The operator has a column 12-2 for displaying a tilt change target amount (described as a target value in the drawing) and a column 12-3 for displaying a tilt adjustment amount (described as an actual measurement value in the diagram) on the tilt adjustment screen. The length of the leveling jack 11 is adjusted so that the values are close.

  Then, the values in the column 12-2 for displaying the tilt change target amount (denoted as the target value in the drawing) and the column 12-3 for displaying the tilt adjustment amount (denoted as the measured value in the diagram) on the tilt adjustment screen. As soon as possible, the operator presses the tilt measurement button on the tilt adjustment screen again. Then, the processing device 124 records a completion flag indicating that the adjustment work for the first displacement has been completed in a memory or the like, and based on the value of the completion flag relating to the other displacement, It is determined whether or not the inclination adjustment work has been completed in the displacement (step S108). If the tilt adjustment work has not been completed for all displacements in the X-axis direction of the table 13, the processing device 124 transmits to the portal machine tool 1 instructing movement control of the table 13 (step S109). The mold machine tool 1 controls the movement of the table 13 to the second displacement. The movement control of the table 13 may be performed manually by the operator instead of being automatically performed by the portal machine tool 1 as described above. Then, the operator adjusts the length of the same leveling jack 11 at each displacement. The processing device 124 outputs the measurement result of the inclinometer 121 at the next displacement to the display device (step S110). And the process of step S108-step S110 is repeated. If it is determined in step 18 that the tilt adjustment work has been completed for all displacements in the X-axis direction of the table 13, the processing device 124 sends a tilt measurement start instruction signal to the portal machine tool 1 via the data recording device 133. The process from step S100 is repeated. As a result, a plurality of tilt adjustment operations are repeated.

As shown in this figure, the tilt measurement screen displays a table position display field 11-1 for displaying the displacement of the table 13 in the X-axis direction, and a roll angle and a pitch angle for each displacement of the table 13 recorded by the data recording device 133.

The measured pitch angle is −11. Further, -x roll and -x pitch in the screen example of FIG. 11 are the roll angle measured by the inclinometer 121-22 installed behind the table 13 in the movement direction in the X-axis direction and the inclination installed behind the movement direction. This is the pitch angle measured by the total 121-21.
On the inclination measurement screen, an inclination state graph 11-3 indicating a roll angle and a pitch angle for each displacement in the X-axis direction is displayed. The inclination state graph 11-3 shows a graph of measurement results of inclination for each X-axis displacement of + x roll, + x pitch, -x roll, and -x pitch. When an operator looks at this graph and determines whether the inclination of the upper surface of the table 13 is within an allowable range, the inclination for each X-axis displacement of + x roll, + x pitch, −x roll, and −x pitch is determined. It is determined whether the tilt angle is within a predetermined range.

As shown in this figure, the tilt adjustment screen includes a table position display column 12-1 for displaying the displacement of the table 13 in the X-axis direction, and a column 12-2 for displaying a tilt change target amount (described as a target value in the drawing). In addition, there is a column 12-3 for displaying the tilt adjustment amount (described as an actual measurement value in the figure).
Note that + x roll, + x pitch, -x roll, and -x pitch in the screen example of FIG. 12 are as described in FIG.

  According to the present embodiment, the stroke sensor 123 of the leveling jack 11 that is necessary for the operator to adjust the inclination of each displacement of the upper surface of the table 13 of the portal machine tool 1 within a predetermined range is necessary. And not. That is, it is not necessary to provide the stroke sensor 123 in the leveling jack 11 arranged in the lower part of the bed of the portal machine tool 1, and the portal machine tool 1 can have a simple configuration.

  Note that the transfer function updating unit 1134 of the processing device 124 performs a process of updating the transfer function recorded in the transfer function storage unit 111 to a relational expression that is closer to the actual situation by the same method as in the other embodiments described above. It may be.

Of the difference (max−min) _b1 between the minimum value and the maximum value of the pitch measured by the total 121, a larger value is calculated as “pitch (full length)” 14-1 (see reference numeral 161 in FIG. 16).
In addition, when calculating the “pitch (part)” 14-2, the inclination state output unit 1138 determines the difference between the maximum value and the minimum value of the pitch angle for each part obtained by dividing the entire length of the bed 12 at a predetermined interval.

<< Eighth Embodiment >>
Hereinafter, embodiments will be described in detail with reference to the drawings.
The machine tool adjustment system according to the above-described embodiment calculates the adjustment amount of the stroke of the leveling jack 11 based on the transfer function indicating the relationship between all the leveling jacks 11 and the inclination of the table 13. On the other hand, when the distance between the adjacent leveling jacks 11 is short, the number of adjustments until the inclination of the table 13 converges within an allowable value may increase. This is because the transfer function is obtained assuming that the rigidity of the components including the leveling jack 11 is linear. On the other hand, the actual stiffness of the leveling jack 11 is non-linear. Specifically, the leveling jack 11 receives a load in the compression direction, but does not receive a load in the tensile direction. Therefore, when the distance between the adjacent leveling jacks 11 is short, when the force in the pulling direction is applied to the leveling jack 11, the leveling jack 11 is in a so-called idle state. For example, when the leveling jack 11 is fixed to the bed 12 and a force in the tensile direction is applied to the leveling jack 11, the leveling jack 11 floats from the floor surface. In the present embodiment, a state in which a load is not applied by applying a force in the tensile direction is referred to as a idle state. When the leveling jack 11 is in an idle state, the load that should be applied to the leveling jack 11 is not actually applied in calculation, and there is a possibility that an error in the inclination of the bed 12 occurs. As a result, the number of adjustments until the inclination of the table 13 converges within the allowable value may increase.

The machine tool adjustment system according to the eighth embodiment can converge the inclination of the table 13 within an allowable value with a small number of adjustments even when the distance between adjacent leveling jacks 11 is short.
FIG. 20 is a block diagram illustrating a configuration of a portal machine tool 1 according to the eighth embodiment. The portal machine tool 1 according to the present embodiment differs from the first embodiment in the transfer function stored in the transfer function storage unit 1111 and has the same configuration.
The transfer function according to the present embodiment is a vector indicating the relationship between the leveling jack 11 constituting the non-interference leveling jack group and the inclination of the table 13. The non-interference leveling jack group is a subset of the leveling jacks 11 provided in the portal machine tool 1. The leveling jacks 11 constituting the non-interference leveling jack group (second support) are leveling jacks 11 that do not become idle by normal adjustment of the height of the other leveling jacks 11 constituting the group. Normal adjustment refers to adjustment within the stroke range assumed for adjustment of the inclination of the table 13. For example, the non-interference leveling jack group is a set based on an odd number of leveling jacks 11 in the X-axis direction. In other words, the leveling jacks 11 constituting the non-interference leveling jack group are the leveling jacks 11 that are targets of calculation of the number of strokes. On the other hand, the leveling jack 11 (first support) that does not constitute the non-interference leveling jack group is the leveling jack 11 that can be idled by normal adjustment of the leveling jack 11 that constitutes the non-interference leveling jack group.

  In addition, the non-interference leveling jack group may include a leveling jack 11 that is in a state of being played by a normal adjustment of the height of the other leveling jacks 11 constituting the group. For example, the leveling jack 11 provided at a location where adjustment is difficult, such as the leveling jack 11 provided inside the column 14, may be included in the non-interference leveling jack group. In this case, the machine tool adjustment system calculates the adjustment amount of each leveling jack 11 so that the adjustment amount of the leveling jack 11 provided at the location where adjustment is difficult becomes zero, so that the adjustment is difficult. The inclination of the table 13 can be kept within the allowable range without adjusting the provided leveling jack 11.

Next, a displacement adjustment method using the portal machine tool 1 according to the first embodiment will be described. FIG. 21 is a flowchart showing a method for adjusting the portal machine tool 1 according to the eighth embodiment.
The worker first adjusts the stroke of the leveling jack 11 that does not constitute the non-interfering leveling jack group among the leveling jacks 11 provided in the portal machine tool 1, and plays the leveling jack 11 that does not constitute the non-interfering leveling jack group. A state is set (step S201). In other words, the worker puts the leveling jack 11 that is not a calculation target into play.

Next, the operator attaches the inclinometer 121 and the displacement sensor 122 to the table 13 of the portal machine tool 1 to be adjusted. However, when the displacement sensor 122 is provided in the portal machine tool 1 from the beginning for detecting the X-axis displacement of the table 13, the attachment work is not necessary.
Next, the operator moves the table 13 of the portal machine tool 1 in the X-axis direction. Thus, the data recording device 133 records the displacement in the X-axis direction and the roll angle and pitch angle of the upper surface of the table 13 for each predetermined displacement in the X-axis direction (step S202). The adjustment value display device 126 displays the roll angle and pitch angle for each displacement of the table 13 recorded by the data recording device 133.

  The operator visually determines whether the inclination of the upper surface of the table 13 displayed on the adjustment value display device 126 is within an allowable range (step S203). That is, the operator determines whether or not all the roll angles and pitch angles for each displacement of the table 13 displayed on the adjustment value display device 126 are values within a predetermined allowable range. Note that this determination may be displayed not to the worker but to the worker by, for example, automatically determining with the processing device 24 and displaying the result on the adjustment target value display device 125.

  When it is determined that the inclination of at least one part of the upper surface of the table 13 displayed on the adjustment value display device 126 is not within the allowable range (step S203: NO), the operator presses a predetermined button, etc. An instruction to start adjustment is input to the portal machine tool 1. The adjustment target value specifying unit 1135 of the portal machine tool 1 that has received the adjustment start instruction generates an inclination matrix P indicating the inclination of the upper surface of the table 13 based on the information recorded by the data recording device 133 (step S204). ).

Next, the adjustment target value specifying unit 1135 reads the transfer function T from the transfer function storage unit 1111 and calculates its pseudo inverse matrix (step S205). Next, the adjustment target value specifying unit 1135 calculates the adjustment value matrix X by multiplying the gradient matrix P generated in step S204 by the pseudo inverse matrix T ⁺ calculated in step S205 (step S206).

  The adjustment target value specifying unit 1135 specifies the value of each element of the adjustment value matrix X as the adjustment target value of each of the leveling jacks 11 constituting the non-interference leveling jack group. Next, the adjustment target value display device 125 displays the adjustment target value of each leveling jack 11 specified by the adjustment target value specifying unit 1135 (step S207).

  Next, the operator attaches the stroke sensor 123 to the leveling jack 11 to be adjusted from now on. The operator adjusts the stroke of the leveling jack 11 so that the stroke value displayed on the adjustment target value display device 125 matches the adjustment target value of each leveling jack 11 displayed on the adjustment target value display device 125 (step). S208). This operation is repeated for all leveling jacks 11 to be adjusted in the non-interference leveling jack group.

  The operator moves the table 13 of the portal machine tool 1 again in the X-axis direction after adjusting the stroke of the leveling jack 11 constituting the non-interference leveling jack group. Thereby, the data recording device 133 records the roll angle and pitch angle of the upper surface of the table 13 for each displacement in the X-axis direction after adjusting the stroke (step S209). The adjustment value display device 126 displays the inclination of the upper surface of the table 13 recorded by the data recording device 133.

  The operator determines whether or not the inclination of the upper surface for each displacement in the X-axis direction of the table 13 displayed on the adjustment value display device 126 is within an allowable range (step S210). When it is determined that the inclination of the upper surface of the table 13 displayed on the adjustment value display device 126 is not within the allowable range in a certain displacement in the X-axis direction (step S210: NO), the operator applies to the portal machine tool 1. To start readjustment. As a result, the transfer function updating unit 1134 to which the readjustment start instruction signal is input, the inclination of the upper surface of the table 13 recorded by the data recording device 133 in step S202 and the table recorded by the data recording device 133 in step S209. A difference with the inclination of the upper surface at each of 13 corresponding displacements is taken (step S211). Thereby, the transfer function updating unit 1134 specifies how much the inclination of the upper surface of the table 13 has actually changed due to the adjustment by the operator.

Next, the transfer function updating unit 1134 changes the actual inclination specified in step S211 and the inclination change obtained from the transfer function T (the value obtained by multiplying the adjustment value of the leveling jack 11 by the transfer function T). ), The transfer function T stored in the transfer function storage unit 111 is updated to a relational expression closer to the actual condition (step S212). The transfer function updating unit 1134 can calculate the change in the actual inclination obtained by actually adjusting the leveling jack 11 from the transfer function T by inputting the adjustment value of the corresponding leveling jack 11. Update.
When the transfer function T stored in the transfer function storage unit 1111 is updated by the transfer function update unit 1134, the process returns to step S204, and the portal machine tool 1 recalculates the adjustment target value.

  On the other hand, when the inclination of the upper surface of the table 13 is within the allowable range in step S203 or S210 (step S203: YES, step S210: YES), the operator does not interfere with the leveling jack 11 of the portal machine tool 1. The stroke of the leveling jack 11 that does not constitute the leveling jack group is adjusted. That is, the operator adjusts the stroke of the leveling jack 11 that is not subject to calculation of the adjustment amount. At this time, the operator adjusts the stroke of the leveling jacks 11 that do not constitute the non-interference leveling jack group so that the inclination of the upper surface of the table 13 does not change (step S213). At this time, the operator adjusts the stroke so that a load in the compression direction is applied to the leveling jack 11 that does not constitute the non-interference leveling jack group. When the operator adjusts the stroke of the leveling jack 11 that does not constitute the non-interference leveling jack group, the leveling process of the portal machine tool 1 is finished.

  Thus, according to this embodiment, the machine tool adjustment system calculates an adjustment amount for making the inclination of the table 13 within an allowable range only by the leveling jacks 11 constituting the non-interference leveling jack group. The operator adjusts the leveling jacks 11 constituting the non-interference leveling jack group based on the adjustment amount calculated by the machine tool adjustment system, and then sets the non-interference leveling jack group so that the inclination of the upper surface of the table 13 does not change. The stroke of the leveling jack 11 that is not configured is adjusted. Thereby, at the time of adjustment in step S208, none of the leveling jacks 11 constituting the non-interference leveling jack group is idle, and an increase in error from the calculation result can be prevented. Further, by adjusting the stroke of the leveling jack 11 that does not constitute the non-interference leveling jack group so that the operator does not change the inclination of the upper surface of the table 13, the inclination of the upper surface of the table 13 is kept within an allowable range. A load in the compression direction can be applied to the leveling jack 11 that does not constitute the non-interference leveling jack group.
